Representation of phase equilibria and densities for complex systems using a van der waals volume translated equation of state with a unifac mixing rule

This work investigated the applicability of the van der Waals cubic equation of state (EoS) with volume translation (vdWt), using the modified Huron-Vidal (MHV2) mixing rule with the UNIFAC (UNIQUAC Functional Activity Coefficients) model for describing phase equi-librium and density data for a seri...

Para la regla de mezcla, se aplicó el método de Huron-Vidal modificado (MHV2), con el modelo UNIFAC (UNIQUAC funcional coefi-ciente de actividad) para describir datos del equilibrio de fases y la densidad para una serie de sistemas complejos; en amplias gamas de temperatura (T) y presión (P). Se encontraron algunas limitaciones en la predicción de los datos experimentales recogidos, por ejemplo, en los sistemas con componentes altamente asociativos, la ecuación vdWt+MHV demostró capacidad para representar de manera satisfactoria, tanto el equilibrio de fases como el comportamiento volumétrico.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/44721Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 34, núm. 3 (2014); 26-30 Ingeniería e Investigación; Vol. 34, núm. 3 (2014); 26-30 2248-8723 0120-5609Chiavone-Filho, Osvaldo and Terron, Luiz Roberto and Foletto, Edson Luiz (2014) Representation of phase equilibria and densities for complex systems using a van der waals volume translated equation of state with a unifac mixing rule.
